Enginer Plug-In conversion for an already Li-Ion car??

    Hi guys!

    First post on this forum. I think it's great! Now I know this is a Prius forum, but I figured that Prius modders would be the most knowledgeable people to ask this question (I tried asking enginer, no answer yet...)

    Basically, I am planning on buying a Ford Fusion Hybrid 2013 (not the plug-in Energi one). This model is equipped with a stock Li-Ion battery, and the top speed for all-EV is already 62 mph. I was wondering if the DC/DC converter from the Enginer kit, which limits the pack's discharge into the stock battery to 14 amps, could simply be removed, considering that the stock and the pack's chemistry is the same. The 2 batteries (1.4 kwh and the added 4kwh) would now directly be plugged in parallel, assuming that the added pack's voltage and the stock battery voltage are the same.

    Removing the DC/DC converter would theoretically allow for regenerative braking into the OEM and added battery pack too, and the EV-only mode of the Enginer would not be capped at the DC/DC limit of 34mph-ish, making this type of modification a much cheaper alternative than other methods, which actually replace the OEM battery (which I don't want, considering the already good battery in the Fusion).

    Do you think this is feasible? What would be the best modification to do in this case?

    I know that Prius owners are the most knowledgeable on the subject, please help!

    There are a few Fusion hybrid with Enginer kits. Enginer kit can be installed onto any PHEV or EV regardless of the stock battery chemistry. The DC/DC converter is the key to partition the energy storage.

    You can't remove the DC/DC converter since the chemistry and voltage of those two packs (stock and Enginer) are different. Due to the limited output of the DC/DC converter, you won't be able to sustain EV only driving for long distance. But you can reach highest EV only speed as in the original stock vehicle design.

    Enginer pack doesn't allow regenerative braking energy to the Enginer pack. it is handled by the stock battery pack.

    The primary goal of Enginer kit is supplementing ICE to reduce gasoline consumption and improving overall MPG at affordable price.
